Description
Technical Field
The invention relates to the field of medical instruments, in particular to an ultrasonic probe frame with good fixity in transcranial Doppler operation.
Background
Transcranial Doppler (TCD) is a non-invasive cerebrovascular disease examination method for detecting the blood flow dynamics and blood flow physiological parameters of intracranial main arteries by using ultrasonic Doppler effect, and by means of pulse Doppler technology and 2MHz transmission frequency, an ultrasonic sound beam can penetrate through a thinner part of a skull to directly trace Doppler signals of the blood flow of the intracranial arteries so as to obtain the blood flow dynamics parameters of the intracranial arteries and reflect the function state of cerebral vessels. For example, in carotid endarterectomy of a patient with severe carotid stenosis, the middle cerebral artery of the patient is monitored by using a dual-channel dual-depth TCD (contact flow detection) whole process, the operation mode (whether diversion is needed after the common carotid artery is blocked or not) is determined by analyzing the obtained Doppler data, anesthesia is guided to adjust the administration dosage, the micro-embolus falling condition in the operation process and whether excessive perfusion exists after the artery is blocked or not are judged, and the stability of the head frame plays a crucial role in the operation process.
When the transcranial Doppler ultrasound apparatus is used for examination, the ultrasonic probe frame is worn on the head of a patient, the patient is in a horizontal position, the ultrasonic probe is fixed on the ultrasonic probe frame and acts on a temporal window of the patient, the temporal window can penetrate through a thinner part and a natural pore canal of the skull to obtain Doppler echo signals of main arteries at the bottom of the skull, then electric signals are transmitted to a display screen, and a doctor observes through the display screen.

When the size of the right ear fixing groove is adjusted, the right butterfly nut 3023 is firstly unscrewed; secondly, the right connecting plate 3021 is slid in the front-rear direction, and in the process, the right chute is slid on the outer wall of the right fixing rod 3022 in the front-rear direction to drive the right arc-shaped plate 301 to slide in the right groove in the front-rear direction until the size of the right ear fixing groove is matched with the ears of the patient; the right wing nut 3023 is then tightened such that the right connector plate 3021 is clamped between the right wing nut 3023 and the right ear cap fastener 30.
As shown in fig. 2, the two fixing frames are respectively installed on the left ear muff fixing member 20 and the right ear muff fixing member 30. The mount includes: mounting plate 501, base plate 502, slide bar 503, and fixing member.
The mounting plates 501 are arranged along the front-back direction, and the rear ends of the two mounting plates 501 are respectively fixed at the front end of the left earcap fixing part 20 and the front end of the right earcap fixing part 30; the sliding rods 503 are arranged along the left and right direction, and the end parts of the two sliding rods 503 are respectively fixed on the opposite sides of the two mounting plates 501; the number of the substrates 502 is two, and the ultrasonic probe 5022 is fixed at the upper end of the substrate 502; the substrate 502 is provided with a through groove 5021 which is communicated left and right along the length direction of the substrate; the width of the through groove 5021 is 1.1 times of the diameter of the sliding rod 503, so that the substrate 502 can be slidably sleeved on the sliding rod 503 along the left-right direction, the substrate 502 can rotate around the sliding rod 503, and the through groove 5021 can slide on the outer wall of the sliding rod 503 along the length direction; the two fixing members are fixed to the two sliding rods 503, respectively, and are used to fix the substrate 502 to the sliding rods 503.
When the ultrasonic probe 5022 is fixed by using the fixing frame, firstly, the through groove 5021 slides on the outer wall of the sliding rod 503 along the length direction of the through groove 5021, and the substrate 502 rotates around the sliding rod 503 until the ultrasonic probe 5022 is opposite to the temporal window of the head of a patient; secondly, the substrate 502 is slid in the left-right direction until the ultrasonic probe 5022 abuts against the temporal window of the head of the patient; finally, the substrate 502 may be fixed by a fixing member.
As shown in fig. 2, the fixing member includes: an outer wing nut 5041 and an inner wing nut 5042; the outer wing nut 5041 and the inner wing nut 5042 are respectively screwed on the sliding rod 503.
When the substrate 502 is fixed on the sliding rod 503, the outer wing nut 5041 and the inner wing nut 5042 are screwed, so that the substrate 502 is clamped between the side of the outer wing nut 5041 facing the mounting plate 501 and the side of the inner wing nut 5042 facing away from the mounting plate 501; through the setting, the left and right positions of the substrate 502 can be adjusted, so that the fixed ultrasonic probe 5022 just abuts against the temporal window of the head of the patient.
As shown in fig. 2, the fixing member further includes a spring 5043. The spring 5043 is sleeved on the sliding rod 503. When the base plate 502 is fixed to the sliding rod 503, the spring 5043 is between the side of the outer wing nut 5041 facing the mounting plate 501 and the side of the base plate 502 facing away from the mounting plate 501.
When the base plate 502 is secured, the outer wing nut 5041 is threaded toward the mounting plate 501 causing the spring 5043 to compress causing the spring 5043 to apply a force to the base plate 502 toward the mounting plate 501 causing the ultrasonic probe 5022 on the base plate 502 to abut against the temporal window of the patient's head. Meanwhile, the spring 5043 can also provide a screwing buffer force, so that the ultrasonic probe 5022 on the base plate 502 can not directly abut against the temporal window of the head of the patient and can cause pain to the patient after the temporal window of the head of the patient is injured.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
